SPECIFICATION forming part of Letters Patent No. 633,689, dated September 26, 1899.

Application filed Tune 2, 1899. Serial No. 719,080, (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN F. DONOVAN, a citizen of the United States, and a residentof Phillips, in the county of Price and State of lVisconsin, have invented certain new and useful Improvements in Stack-Roofs; and I do hereby declare that the followingis a full, clear, and exact description thereof.

My invention has especial reference to devices for protect-ing stacks of hay, straw, or grain from rain or snow; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter and subsequently claimed.

In the drawings, Figure l is a representation of a stack of hay, straw, or grain protected bymy device, the roof-boards being shown in section. Fig. 2 is an inner side elevation showing two of the separable roofboards and their connecting attachments.

Referring to the drawings, A represents in outline a stack of hay, straw, or grain, and B B B the separable roof-boards, there being also two boards (marked O O) which are united together at an angle to form the top of the roof, from which top the remainder of the boards are suspended, as shown. Each of the separable roof-boards B is provided, near each end thereof and on the inner or under side, with a connecting-strap D, said straps being preferably formed of strips of flat metal bent at an angle, as shown at b, near their upper ends, so as to form an offsetted upper end c, which latter is further provided with a transverse slot d, and the lower ends of said straps are bent outwardly to form heels e for better support of the boards B, to which said straps D are secured, as by nails or screws ff. Near its lower end each strap D is punched to form an inwardly-projecting bent catch or lip g for engagement with the slot d in the strap of the adjacent board.

The united top boards C O are provided on the under side and near each end thereof with a doubled strap E, the lower ends of which are formed with heels e and lips g, corresponding to those of the individual straps D.

In applying a roof to a stack the top C is first placed upon the apex of the stack, and then the two upper boards B B are suspended therefrom, as shown in Fig. l, by hooking the slotted upper ends of the straps on said boards to the lips g g on the doubled straps E, the upper edges of said boards B B beingbeneath the lower edges of the top boards C C, as shown, and then other boards B B are similarly attached to and beneath the lower edges of the uppermost of the separable boards B B, and so on, using as many of said separable boards B B as the size of the stack requires, ordinarily only the sloping upper part of a stack requiring such protection. The lowest pair of boards B B may be held to place in any suitable manner-as, for instance, by means of cords, ropes, or chains F F, secured to the lips g g of the straps D D on said boards, and heavy weights G G at the lower ends of said cords, ropes, or chains-and it is obvious that the latter may be fastened to stakes driven in the ground, if desired, as indicated by dotted lines in Fig. l, to aid in keeping the roof upon the stack. Inasmuch as all the boards are provided with the described connecting-straps all in line with each other at each end it will be apparent that a stack can be very quicklyroofed over with my' devices and the said roof as readily removed when desired, without the necessity of any change in or addition to the sairie or the use of any tools or nails and that the said device can be used season after season without alter ation and will occupy very little space in storage when not in use.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a stack-roof, the combination with an angular top piece provided with doubled straps transversely secured to the underside and adjacent to each end thereof, the lower ends of said doubled straps being bent upward to form heels, in engagement with the lower edges of said angular top piece, of a series of separable or removable boards, each havin g straps secured transversely to the under side and adjacent to each end thereof, said straps being bent upward at each end to engage with the upper and lower edges of said board, and the upper end of each strap projecting in line with, and iush with the upper surface of, said board, and provided IOO with a perforation, and each strap having' a downward-extending and upWard-projecting lip intermediate of its ends.

2. In a stack-roof, the combination of a series of separable 0r removable roof-boards, each having straps secured transversely to the under side and adjacent to each end thereof, said straps being bent upward at each end to engage With the upper and lower edges of said board, and the upper end of each strap projecting in line with, and ush with the upper surface of, said board, and provided with a perforation, and each strap having a downWard-extending and upward-projecting lip intermediate of its ends.

o. A strap for attachment to the roof-boards of a stack-roof consisting of a flat metallic plate bent upward at each end, the npperend extending beyond the line of said bend and having a perforation therethrough, and there being an integral lip punched from said strap intermediate of its ends.

y In testimony that I claim the foregoing I have hereunto set my hand, at Chicago, in the county of Cook and State of Illinois, in the presence of two Witnesses.
